Uptake of Sulfate from Ambient Water by Freshwater Animals.

ABSTRACT: To better understand how the sulfate (SO₄ ^2-) anion may contribute to the adverse effects associated with elevated ionic strength or salinity in freshwaters, we measured the uptake and efflux of SO₄ ^2- in four freshwater species: the fathead minnow (Pimephales promelas, Teleostei: Cyprinidae), paper pondshell (Utterbackia imbecillis, Bivalvia: Unionidae), red swamp crayfish (Procambarus clarkii, Crustacea: Cambaridae), and two-lined mayfly (Hexagenia bilineata, Insecta: Ephemeridae). Using δ( ³⁴ S/ ³² S) stable isotope ratios and the concentrations of S and SO₄ ^2-, we measured the SO₄ ^2- influx rate (J _in
